From the picturesque hill of Devichiy, located near the village of Kushnarenkovo in Bashkortostan, a stunning view of the Belaya River opens up. Perhaps this is why the nobleman Andrey Stepanovich Topornin decided to build his estate here. He inherited this land from his father, who was awarded it for his service to the tsar and the Motherland. The other nearby plots were acquired by Topornin himself, uniting three Russian villages into one, named Stepanovka.

The estate was built in a strict classical style. Inside, the rooms and halls were furnished with expensive furniture, the walls adorned with beautiful paintings, and the fireplace, it is said, was designed by a French architect invited from St. Petersburg. The heating system of the house was quite original, utilizing a complex system of water-heating pipes. Next to the estate, a fruit orchard was planted, with alleys, benches, and gazebos arranged. According to legend, in 1824, Alexander I stayed at Andrey Topornin's house while traveling through these areas and passing by the estate.

In 1865, the estate gained a new owner, merchant Mikhail Gribushin. There is a story that while floating down the Belaya River, he was so enchanted by this place that he decided to purchase it. When he approached Topornin's heirs, he offered to buy the estate for any price. The owner named a high sum, but Gribushin, smirking, pulled a large amount of money from his boot and paid immediately.

The new owner established a tea packaging business here, planted over a hundred fruit trees, and built a pier on the shore. This pier was the main one in Bashkortostan for some time. After the October Revolution of 1917, the estate was nationalized. During the Great Patriotic War, a secret school for training saboteurs operated here, and later, a vocational school. In 1994, a severe fire caused significant damage to the building. Nevertheless, the estate was built so sturdily that it still stands today, although it looks like ruins.
